Digital Twins for Validation of Dynamic Performance & Reliability of Motion Systems

Challenge

The validation of dynamic performance & reliability of motion systems is costly and tedious. We will have to deal with:

  • Design variability (e.g. geometry size, power, hardware) due to customization; 
  • Inherent component variability (e.g. mechanical tolerances);
  • Variable parameter settings/operation in smart products;
  • Mission profiles like load conditions and usage conditions;

Barriers in order to more effectively validate new products/prototypes in this context:

  1. Some dynamic component interactions are still unknown or not modelled, although they are key for accurate HIL testing to find & search harmful component combinations;
  2. Lack of access to and usage of real operation conditions for relevant HIL testing;
  3. Lack of methods to effectively validate motion systems in this large ‘motion system-environmental’ variants space.

Project goals

With this project we will develop a framework to minimize the validation cost and time of new motion product variants and/or products used in different mission profiles. In view of the total unit cost of performance, the framework should allow to validate performance and assess lifetime of a (variant) motion product for a variable mission profile, based on capturing data from a fleet of drivetrains. The four enabling innovation goals are to:

  1. Capture & extract the required information of existing products and mission profiles: 
    1. Into the form of a digital twin of the product and the mission profile (load, environment,…); 
    2. Built up based on state of the art models and (historic) data from the lab (fleet of drivetrains) or from the field.
  2. Extrapolate this information in a multitude of dimensions:
    1. By transforming the information into parametrized system level digital twins joining insights from:
      1. Physics based system models assembled based on scalable models of components and their interactions;
      2. Data driven system models enhanced with physical insights (models).
  3. Design and validate product validation strategies:
    1. Improved HIL testing with dynamic component interaction knowledge;
    2. Improved full system testing of the EM behaviour (torques, speeds, voltages, currents, … ) leading to an assessment of the expected lifetime.
  4. Define a method for assessing the trustworthiness of the validation strategy.
